After changing the fluid and filter, the truck runs just like new. Could not be happier

Lovin' it! We'll see how it does over the long haul, but had numerous transmission shift fault codes, neither led myself or a more experience gearhead to believe the tranny in my Chevy 2500 HD was failing, just had some intermittent quirks. With that, I made the shift to AMSOIL when it was decided upon to change the tranny fuel, especially not knowing if the reseller business had performed the task since the Chevy was nearing 50k miles. Went with a deep pan and filter, added LOTS of AMSOIL tranny fluid, and no more intermittent fault codes, slightly better gas mileage, better shifting, and lower tranny temps. Purely not saying AMSOIL is a tranny repair recommendation, but in my particular case it's all relative.

One I call the best of all oil never had problems. I have 2017 Malibu my car rans okay & rougher be for I changed oil I took my car to be tested on a dino, I think I spelled it wright if not sorry anyways found with the oil I had in the car at running at 80 MILES my RPMS WAS 3200, After changing to Amzoil at 80 MILES RPMS dropped 2700 to me that's a big difference the other oil that I can't say is one of top brands.

I drained and refilled 4 times, driving a few days in between each change. It cleared up the shuddering on my Honda that has 240k miles, giving the transmission a new lease on life.

Looked right, smelled right, great service and website. My Duramax and Allison seemed happy in the short term.

I have been using Amsoil for 5 years in my 6.7 cummins. Truck runs great. My 2011 ram with 6.7 has 300,000 miles on it. I change the filters every 20k and the Amsoil every 40,000 . The engine has been bullet proof . GREAT PRODUCTD

Full disclosure. I don't know if Amsoil is the best oil on the market because I'm not a chemist. But I do know that I trust the Amsoil brand more than any other in the industry. When it comes recommended by guys that push 2k+ hp through their Cummins, I trust it will be just fine in mine. I will continue to use Amsoil exclusively in every component of my truck because I believe it's the best I can get.

Makes the Taurus shift silky smooth!

Use on every scheduled maintenance

When I need a product that you don't need very often, i.e., ATF, I will always go to Amsoil because I can trust the product to be what it is supposed to be and more. I will always trust all their products to not only protect my equipment while it is operating but to protect it while in storage from corrosion.

My trans has over 200k miles on it. After the service (I did myself). the old trans feels really strong. I was having some hard shifting when it got hot. That went away. I should have switched to amsoil 150k ago. I use amsoil in my Harley and Indian too. I use amsoil gun oil.

This oil is so smooth, after doing the trans flush, The Rav shifting is like when it was new... Great oil....

the tranny in my wifes car doesn't shift so hard now.

Used on a fresh rebuild and new converter. Works as advertised no slipping ,chattering. Have only put a few hundred miles on it since, working flawlessly. I expect great things from amsoil. This was a gift to a family member.

Bought a case of the OE fluid to replace a friends Toyota ATF. I flushed the old out and changed the filter. The old was already burnt smelling and shifting poorly. It has been working fine since it was changed.

Used lots of Amsoil products over the years, from my Ford Powerstrokes to my lawnmowers. Always had good use and performance from them. Will absolutely continue using Amsoil products.

All products are great

I've been using the OE ATF on my personal vehicles for several years in the power steering and transmission. It's an affordable alternative to the best grade of Amsoil ATFs. This was used to replace someone else almost burnt fluid. So far it's shifting regular.

good product
